In this work, we abstract the decoding of a user's packet using an SINR-threshold model.
That is, if the SINR of a packet in a given RE in any decoding iteration exceeds a threshold \(\gamma _{\text{th}}\) , then the packet can be decoded correctly [1]}, [2]}.
Packet capture occurs when a packet can be decoded correctly as per the SINR-threshold model, even though it collides with another packet, and is thus considered a good abstraction of the decoding in the physical layer.
